VR-TV is auto real-time volume regulator for household TV (computer). Its advanced audio frequency signal processing technology adjusts volume automatically after one setting, so consistent volume will be gained no matter what its audio frequency source is. It can access one or two groups of sources with stereo RCA plugs, like satellite TV set-top-box (STB) or cable digital TV STB, DVD player, Karaoke-On-Demand (KOD) player (Karaoke player, Karaoke machine, Jukebox)and computer. Any two of those audio outputs are sent to two interfaces on VR-TV. This machine has one RCA output interface and one 3.5mm stereo output interface, which are selected by the switch on top and then sent to TV or power amplifier, multimedia loudspeaker and earphone. VR-TV takes sampling and controls the outputs for both left and right tracks; it will amplify *0dB automatically if the sound signal is too small, and attenuate at least *2dB if the sound signal is too big. It has power switch, BYPASS switch, one-out-of-two switch, output one-out-of-two switch, power indicator, round volume knob on the top of VR-TV. This machine is serially connected with player or TV (or computer’s multimedia active loudspeaker), so the volume can be regulated automatically during switching stations, videos, songs or ads. It has auto balance function for left and right track and buffering function. Audio output is adjustable among **0.7V and its auto balance range is 0.*5V*7V while keeping music dynamic. This machine can be placed on the top of other chassis and get electricity from power adaptor. If it works together with computer, its round output volume knob on its top is used to adjust the output volume without changing any computer setting.
